How do you convert a jQuery object into a string?如何将 jQuery object 转换为字符串?
I assume you're asking for the full HTML string.我假设您要的是完整的 HTML 字符串。 If that's the case, something like this will do the trick:
如果是这样的话,这样的事情就可以解决问题:
$('<div>').append($('#item-of-interest').clone()).html();
This is explained in more depth here , but essentially you make a new node to wrap the item of interest, do the manipulations, remove it, and grab the HTML.这在此处进行了更深入的解释,但本质上是您创建一个新节点来包装感兴趣的项目,进行操作,将其删除,然后抓取 HTML。
If you're just after a string representation, then go with new String(obj)
.如果您只是在字符串表示之后,那么 go 和
new String(obj)
。
I wrote the original answer in 2009. As of 2014, most major browsers now support outerHTML
as a native property (see, for example, Firefox and Internet Explorer ), so you can do:我在 2009 年写了原始答案。截至 2014 年,大多数主流浏览器现在都支持
outerHTML
作为本机属性(例如,参见 Firefox和Internet Explorer ),所以你可以这样做:
$('#item-of-interest').prop('outerHTML');
With jQuery 1.6, this seems to be a more elegant solution:使用 jQuery 1.6,这似乎是一个更优雅的解决方案:
$('#element-of-interest').prop('outerHTML');
Just use.get(0) to grab the native element, and get its outerHTML property:只需使用 .get(0) 获取原生元素,并获取其 outerHTML 属性:
var $elem = $('<a href="#">Some element</a>');
console.log("HTML is: " + $elem.get(0).outerHTML);
The best way to find out what properties and methods are available to an HTML node (object) is to do something like:找出 HTML 节点(对象)可用的属性和方法的最佳方法是执行以下操作:
console.log($("#my-node"));
From jQuery 1.6+ you can just use outerHTML to include the HTML tags in your string output:从 jQuery 1.6+ 起,您可以使用 outerHTML 在字符串 output 中包含 HTML 标记:
var node = $("#my-node").outerHTML;
jQuery is up in here, so: jQuery 在这里,所以:
jQuery.fn.goodOLauterHTML= function() {
return $('<a></a>').append( this.clone() ).html();
}
Return all that HTML stuff:返回所有 HTML 的东西:
$('div' /*elys with HTML text stuff that you want */ ).goodOLauterHTML(); // alerts tags and all
This seems to work fine for me:这对我来说似乎很好用:
$("#id")[0].outerHTML
The accepted answer doesn't cover text nodes (undefined is printed out).接受的答案不包括文本节点(未定义被打印出来)。
This code snippet solves it:此代码段解决了它:
var htmlElements = $('<p><a href="http://google.com">google</a></p>↵↵<p><a href="http://bing.com">bing</a></p>'), htmlString = ''; htmlElements.each(function () { var element = $(this).get(0); if (element.nodeType === Node.ELEMENT_NODE) { htmlString += element.outerHTML; } else if (element.nodeType === Node.TEXT_NODE) { htmlString += element.nodeValue; } }); alert('String html: ' + htmlString);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
No need to clone and add to the DOM to use.html(), you can do:无需克隆并添加到 DOM 即可使用.html(),您可以这样做:
$('#item-of-interest').wrap('<div></div>').html()
It may be possible to use the jQuery.makeArray(obj)
utility function:可以使用
jQuery.makeArray(obj)
实用程序 function:
var obj = $('<p />',{'class':'className'}).html('peekaboo');
var objArr = $.makeArray(obj);
var plainText = objArr[0];
If you want to stringify an HTML element in order to pass it somewhere and parse it back to an element try by creating a unique query for the element:如果要对 HTML 元素进行字符串化,以便将其传递到某处并将其解析回元素,请尝试为该元素创建一个唯一查询:
// 'e' is a circular object that can't be stringify
var e = document.getElementById('MyElement')
// now 'e_str' is a unique query for this element that can be stringify
var e_str = e.tagName
+ ( e.id != "" ? "#" + e.id : "")
+ ( e.className != "" ? "." + e.className.replace(' ','.') : "");
//now you can stringify your element to JSON string
var e_json = JSON.stringify({
'element': e_str
})
than比
//parse it back to an object
var obj = JSON.parse( e_json )
//finally connect the 'obj.element' varible to it's element
obj.element = document.querySelector( obj.element )
//now the 'obj.element' is the actual element and you can click it for example:
obj.element.click();
